(53 + 12) / 77 = 0.84
65/77 = 0.84
0.84 = 0.84 (correct)
so u would have to add 12
Answer:
yes, (-3, 2) is a solution
Step-by-step explanation:
72 + 9y > - 3
9y > - 72 - 3
9y > - 75
y > - 75/9
y > - 25/3
y > - 8. (3)
y ∈ (-8.0(3) ; +oo)
(-3, 2) ⊂ (-8.0(3) ; +oo)
Answer:
9
Step-by-step explanation:
If you take a look at the graph, in order to find h(-5) you need to look at what the y intercept is when x=-5. In that case, when x = -5, y = 4 and so h(-5) = 4.
You do the same for h(5). Look at what y is when x equals 5. So h(5) = 5.
h(-5) + h(5) = (4) + (5) = 9
Your equation is:
(x + 2)² + (y + 2)² = 36
Answer:
a)
b)d(t)=500t
c)
Step-by-step explanation:
d = Horizontal distance
s = the distance between the plane and the radar station
The horizontal distance (d), the one mile altitude, and s form a right triangle.
So, use Pythagoras theorem


a) 
(b) Express d as a function of the time t (in hours) that the plane has flown.

d(t)=500t
(c) Use composition to express s as a function of t.

using b
